JOHN FARKAS AND CHARLES H. GBIESER, OF DETBOIT, MICHIGAN, ASSIGNORSFTO DETROIT AUTO FUELIZEB COMPANY, OF DETROIT,

OF MICHIGAN.

MICHIGAN, A CORPORATION HOMOGENIZER.

Application filed January 24,1521. Serial No. 439,515.

To all whom it may concern Be it known that we, JOHN FARKAS and (humans H. GRIESER, both citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Homogenizers, of

which the following is a specification, reference being had therein to the accompanying m drawings.

The invention relates to means for producing a homogeneous combustible mixture for use in internal combustion engines and consists in the novel construction as hereinafter h set forth.

In the drawings:

Figure 1 is a sectional elevation of the intake conduit for an internal combustion engine provided with my improved construction:

Figure 2 is a horizontal section on line 22 of Figure 1;

Figure 3 is a view similar to Figure 1 partly in elevation and showing a modified construction Figure 4 is a vertical section in a plane transverse to Figure l.

A is the intake manifold of an internal combustion engine having the vertical portion B with an elbow C at its lower end for connection with the carburetor (not shown). A portion of the conduit B is somewhat enlarged in diameter and is surrounded with a jacket D, which is connected by a conduit E with the exhaust manifold F. G and H are rotary fans or propellers arranged within the enlarged portion of the conduit and inserted therein through a lateral opening closed by acover plate I. These propellers are mounted on a common shaft J which is journaled within the intake and the propeller H is so proportioned as to be of greater power than the propeller G and has oppositely arranged blades. The arrangement is such that the velocity of gases passing through the intake operating upon the propeller II will cause the rotation thereof, while the propeller G will be driven by the propeller H and will partly, but not com pletely, oppose the movement thereof. Consequently, the combined effect is to throw the gases outward against the peripheral wall of the chamber and any unvaporized fuel carried thereby will come in contact with the surface heated by the jacket 1).

THE

To supply initialheat so as to facilitate the starting of the engine, an electric heater K is preferably arranged in thei intake. This, as shown in F igure-2, is, arranged within a recess in the cover plate I and therefore comes in contact with ;.the ;fue1 thrown outward by the fans. In Figure 3, a modified construction is illustrated, in which the heater L is arranged around a shank L and is mounted upon a detachable pl'ug M, which also forms a bearing for one end of said shank L. With both constructions suflicient heat is imparted to the mixture to vaporize a part of the liquid fuel and therefore to start the engine, after which the exhaust heat in the jacket D will continue the vaporization.

In operation, the cranking of the engine will be sufficient to start the rotation of the propellers G and H and as soon as the engine starts and the mixture increases in velocity through the intake, these propellers will be rapidly revolved. This will effectually agitate and commingle the air and liquid fuel, while the unvaporized fuel by being thrown into cont-act with the heated wall will be vaporized thereby.

WVhat we claim as our invention is:

1. The combination with an intake of an internal combustion engine, of an enlargemerit in said intake, a rotary member having its axis arranged longitudinally of said intake and provided with a pair of propellers having their blades opposed to each other, one of said propellers being of greater power than the other, and means for heating the peripheral wall of said enlarged chamber.

2. The combination with an intake of an internal combustion engine, of an enlarged chamber in said intake, adapted to receive fuel means for heating the fuel in said chamber and a rotary member within said enlarged chamber comprising a shaft, a pair of propellers mounted thereon having the blades thereof opposed to each other, one of said propellers being of greater power than the other and adapted to revolve said shaftagainst the resistance of the other propeller, whereby the combined effect is to throw the liquid fuel in suspension in the mixture against the heated Wall.

3. The combination with an intake of an lers secured to said member and having their blades: arranged to opposeeach other, the blades of one propeller being Wider than the blades of the other propeller to overcome theresi'stanc'e thereof and actuate the same.

pellershaving opposed blades, one of said propellers being of greater power than the 1 other, and meansfor heating the -mixture of air and'fuel i-n said enlarged chamber.

5. The combination with an intake of an internal combustion engine, of an enlarged chamber therein, a jacket surrounding and Spaced from said enlarged chamber, a rotary member in said enlarged chamber co1nprising a pair of propellershaving the blades thereof opposed to each other, one of said propellers being of greater power than the other, and means for conveying a heating fluid to the spacebetween said enlarged chamber and said acket to heat the peripheral Wall of said enlarged chamber.

In testimony Whereofwe affix our signatures.
